NGSS 5-PS1-3: Make observations and measurements to identify materials based on their properties.
If your students have already learned the meaning of volume and mass, you can easily use those terms to define density as Density = mass/volume and then use those terms in the lesson. We are also using “heavy”, “light”, and “weight” instead of “mass”. Note: We are purposely using the terms “size” and “amount” instead of “volume” in discussions of density. Density is a characteristic property of a substance and doesn’t depend on the amount of substance.If an object is more dense than water it will sink when placed in water, and if it is less dense than water it will float.Density is a measure of how heavy something is compared to its size.Students will also be able to explain that density is a characteristic property of a substance. So, like the Beverley Hillbillies, "they loaded up the truck.".Students will be able to explain that the density of a substance has to do with how heavy it is compared to the size of the object. And if you think about it, real estate listings will specify whether or not the sellers are leaving the washer/dryer, fridge, and so on. I suggest this because when we bought out house, we learned that when the owners in the 70s moved out, they took everything, including the light fixtures in the front hall. Seems like it would be the other way around: the only thing that people did NOT move with them when they shifted houses was the kitchen sink, which was plumbed in. Jacques Boutard, retired English teacher September 19, 2019 It was possible, by the 1880s, to replace the dry or wet trough of stone, wood, or zinc-lined wood (nicknamed the “zinc”) with an enamelled cast iron, granite, steel, or slate trough with cock-taps for running water." Our price is right.” So promised Russill Hill Hardware in its Toronto Star advertisement of May 9, 1902. Try this : “If your kitchen sink is worn out, replace it with a steel or graniteware sink. Never trust moms, or newspapers, blindly. Nelwyn Talley, obviously your mom didn't know what she was talking about. Old Sears Roebuck catalogs carried just about everything, but in my research of those catalogs I find that they did not sell kitchen sinks. The depression destroyed the industry when the economy crashed. everything from tea cups to a grand 12 piece dining room suite. Sears promoted this all inclusive home value to sell what furnished the interior of the homes. The advertising stated, "Everything is included, even the kitchen sink." This made apprehensive buyers feel at ease knowing there was very little guesswork involved in ordering a Sears home. Sears Roebucks sold mail order homes through their catalogue 1900-1937. "I believe the saying came from the 50’s because my mom told me that the houses did not have kitchen sinks & they would bring their own kitchen sink each time they moved to a new house," How can the saying have originated in the 1950s if it was in use before then? 'we move everything except the kitchen stove.' "The earliest recorded stove was created in Alsace, France in 1490." I would surmise that the early stoves were either built in AND/OR difficult to move so were left behind when people left their houses. The current phrase probably evolved this earlier phrase. Another variant of the phrase, “everything but the kitchen stove” predates this phrase and can be found in 1894 in the Jeffersonville National Democraft. This lead to the erroneous belief that the phrase originated during WWII. The expression became popular during World War II, where it was said that everything but the kitchen sink was thrown at the enemy. Origin The phrase originated around the early 1900s and the first print reference can be found in 1918 in the newspaper The Syracuse Herald. When he and his colleague went on a trip to a remote place for work, he insisted on taking everything but the kitchen sink along.You’ll find everything but the kitchen sink in there. When we were going on a vacation, my wife wanted to take everything but the kitchen sink.
It talks of everything but the kitchen sink.
